This Extreme Leather Utility Bondage Collar is 2½” wide and is fitted with 4 solid 6mm thick welded Heavy D-rings. The leather used for this bondage collar is water buffalo which is very supple yet extremely strong and hard wearing. The edges of the leather collar are beveled for comfort and beauty. The welded Dee rings are riveted onto the slave Collar using 10mm long rivets with a 1¼” wide leather strap. There is also 2 pairs of D-lugs riveted on the bondage collar for further fetish attachments. In the back of the bondage collar is a 1¼” wide Heavy Roller Buckle. I have many other Bondage Accessories that would be great to use with this collar so check out that page. This bondage collar also comes in red-trim so please check out my leather Information page for more details.
